Pyfluent for running jobs on HPC using PBS scheduler
Good morning, just a quick question, sorry for not adding further details. I have a case/dat file, already initialized, with 100 iterations made. I save these files and try to continue to iterate using 2 approaches: 1) read the files through a journal and launch fluent using a jobscript for PBS scheduler 2) read the files…

PyFluent: How to get the zone ID when zone name is known?
I know that I can get face and cell zones with solver.setup.boundary_conditions.get_state() solver.setup.cell_zone_conditions.get_state() From this I can get the names. But some commands require to use the ID (a number) instead, for example…

UDFs for modelling heat transfer in a porous medium
Hello, I am unsure if this is the place to ask this, however I am really struggling to create UDFs to fit a numerical model which must be applied as UDFs in ANSYS Fluent to model a phase change material in a porous medium. I have attached the mathematical model I am trying to follow as well as my current code. I am…

How to make discharge curves (voltage vs cell capacity) using the MSMD module?
I am validating one of my models for a 20Ah battery. I am giving a 1 C rate discharge and want to check the discharge characteristics plotted as cell voltage vs battery capacity in Ah. I cant figure out how to make this plot in fluent. I am using the ECM model btw. I also want temperature to be plotted along capacity.

Issue in opening a gui on remote machine
when using the launch_fluent on remote machine from app service , gui is not getting open. Instead it is running in the background. But I need to get space claim open to do the necessary modification on geometry and then send it to fluent. Any suggestion will be really appreciated. I am using ssh for the connection

How can I rename xy, yz, zx planes so that the name reflects their current location?
When creating groups of planes of a constant x, y, z location the name is zeroed on the first specified value and the remaining planes names are defined by the offset from the zero value. For example, 3 planes equally spaced by 0.1m starting from 1m or 3m would be named x-plane=0, x-plane=0.1, x-plane=0.2. How can planes…

How can I rename isosurfaces and planes to round off names at selected number of significant digits?
Sometimes when creating groups of iso-surfaces or planes of a constant x, y, z location sometimes the name of the object can contain unexpected digits in it. For example, 3 x-constant isosurfaces with spacing 0.1 starting at 1m could produce names such as constant-x=1, constant-x=1.10000001, constant-x=1.2. How can this be…

pyFluent - Returns zone names while meshing
Hi! I have been trying to construct a 'smart' meshing process which would query label/zone names and issue surface refinement depending on said names. Is there a command whose output would be all the zone names in a table or something? Same question at but for the solver instead of the mesher. Thanks you for your time!…
